Perceptual and semantic priming in patients with multiple sclerosis: is implicit memory preserved?
Mechanisms of difficulties in perceptual priming depending on course of MS and methodological aspects of the priming procedure are discussed.
A longitudinal study of cognition in primary progressive multiple sclerosis.
Results indicated that initial cognitive status on entry into the study was a good predictor of cognitive ability at 2 years, and there was only a small number of significant correlations between changes in cognition and changes on MRI.
Effects of cannabis on cognitive function in patients with multiple sclerosis
This cross-sectional study provides empirical evidence that prolonged use of inhaled or ingested street cannabis in patients with MS is associated with poorer performance on cognitive domains commonly affected in this population.
Cognitive impairments in relapsing-remitting multiple sclerosis: a meta-analysis
There was a moderate decline in cognitive functioning in individuals with RRMS compared with healthy controls and age and gender were moderators of cognitive impairment in all cognitive domains, whereas neurological disability and disease duration primarily moderated performance on tasks assessing memory and learning.
Benign multiple sclerosis
Current definitions of benign MS may overestimate this entity, since they are mainly weighted for the patients’ motor abilities and fail to capture relevant disease-related cognitive, psychological and social problems.
Neuropsychiatric manifestations of multiple sclerosis
Cognitive domains discussed include general cognitive functioning, learning and memory ability, attention, processing speed, executive functioning, visual perceptual ability and language functioning, and factors pertaining to pediatric populations in multiple sclerosis are addressed.
Characterizing cognitive deficits and potential predictors in multiple sclerosis: A large nationwide study applying Brief International Cognitive Assessment for Multiple Sclerosis in standard clinical care.
Regression modelling revealed that disease subtype, long disease duration, high physical disability, unemployment, low educational level, high age, male sex, and the absence of current disease-modifying treatment were important predictors for worse BICAMS' test performance.
Incidental learning during rapid information processing on the symbol-digit modalities test.
A computerized version of the Symbol--Digit Modalities Test was developed that scored participants' performance during subintervals over the course of the usual 90-s time period and also added an incidental learning test (c-ILT) to assess how well participants learned the symbol-digit associations while completing the c-SDMT.
Can we define a rehabilitation strategy for cognitive impairment in progressive multiple sclerosis? A critical appraisal
A specific approach in assessing CI and in designing and administering rehabilitation training for patients with progressive forms of MS is needed.
Alteraciones cognitivas en la esclerosis múltiple
SUMMARY. The cognitive impairment in multiple sclerosis is a great concern due to its prevalence, which oscillates from 40 to 60% and because it affects the quality of life of the patients who suffer


Implicit memory in multiple sclerosis.
Results showed that implicit memory was not significantly impaired in the MS subjects, and that they were impaired on recall but not recognition, and suggest the possibility of long-term priming of implicit memory in the control subjects.
Semantic priming in multiple sclerosis.
Previous studies have demonstrated that some patients with multiple sclerosis (MS) exhibit a broad spectrum of deficits in access to lexical and semantic information, including impairments on verbal
Memory dissociation and metamemory in multiple sclerosis
On the nature of memory disturbance in multiple sclerosis.
The results suggest that the memory disturbance in MS results primarily from an imparied ability to access information from secondary memory, while encoding and storage capacity is intact.
Memory impairment in multiple sclerosis
Awareness of Remembering Achieved through Automatic and Conscious Processes in Multiple Sclerosis
Application of the process dissociation procedure to the word stem task demonstrated that conscious and unconscious processes both contribute to remembering in multiple sclerosis.
Repetition priming in normal aging and Alzheimer's disease: a review of findings and theories.
A comprehensive review of the literature on repetition priming in normal aging and Alzheimer's disease is provided to articulate the issues that are critical to interpreting the empirical results, and discuss what new conclusions are suggested by the overall pattern of findings.
Double Dissociation Between Memory Systems Underlying Explicit and Implicit Memory in the Human Brain
A patient who has a lesion in the right occipital lobe and who showed intact explicit and impaired implicit memory for words is presented and indicates that separate processing systems mediate these two forms of memory, and that a memory system in right Occipital cortex mediates implicit visual memory for Words.
Visual Implicit Memory in the Left Hemisphere: Evidence From Patients With Callosotomies and Right Occipital Lobe Lesions
The results indicate that the right occipital lobe does not play a necessary role in visual implicit memory, and that the isolated left hemisphere can support normal levels of visual priming in a variety of tasks.
Memory disturbance in chronic progressive multiple sclerosis.
Patients with chronic progressive multiple sclerosis were compared with age- and education-matched control groups on a battery of clinical and experimental memory measures and showed mild memory disturbance, associated with a greater use of psychotropic medications and a higher incidence of reactive depression.
